Anybody considered Line-X or Arma in the wheel wells?

Pushing_Tin

Just wondering if anybody has given thought to having some truck bedliner coating sprayed in the wheel wells, the back specifically. Doesn't seem like it would cost much or add much weight, maybe 10lbs total? Seems like the deadening of the rocks and road noise might be worth it.


Discuss.

I wont be able to hear the road over my music lol. But line-x is still plastic and you will probly hear it just as much. If you really wanted to you could use what we do for car audio "dynamat".

I don't know about the rear wheel wells, but be aware that there is wiring that routes underneath the fender liners in the front wheel wells. So I'm not sure you want to seal that area off, should you need to access the wiring one day.

The idea would only work as much as it damped the metal. The idea sounds like it might work okay. The best approach would most likely be on the "dry side" with a bond on mass tape. Depending on the properties (mass versus insulation) of the stuff used for acoustics installations that may be sufficiet although adding mass will really reduce the panels vibration due to the impacting of pebbles/sand.

I know, no real answer, just stuff to think about............

10 pounds???!?!?!?! why so heavy?!?

I was trying to shave off some weight from changing the exhaust and intake and such and that will do me just a few pounds.

I drive my car to work, I may do one track day a year for fun. I'd rather not listen to the road noise and rocks flying up inside the wheel wells the other 364 days a year.

Here is what you are looking for: 3M™ Underseal™ Rubberized Undercoating, 08883



Take off your rear wheel, mask, prep/clean, and spray this coating on as it will help in what you want to accomplish; Line-X, et al, dries too hard. The 3M product is flexible and will not fall off the inner wheel liner. You will be establishing a different layer to help dissipate/absorb the sound wave as it travels through both the rubberized coating and the wheel liner; plus this should actually adhere to the liner.

Thanks SoCal, did you do this, or are you planning to?

The road noise on the concrete portion with the rain grooves of the interstate here is reason enough to do this for us. There was one review of the 370Z where they mentioned that the 18" wheels were quieter than the 19" wheels. Yes, I will probably do this too as ours is not a track car—it's a daily driver. It's the easiest solution, and the best bang for the buck without having to disassemble items to do other soundproofing.

+1 as always good info

This is a great idea SoCal - thanks for the info and look forward to a review once you get the coating done.

FWIW, anyone planning to use this product should know how to "prep" the surface onto which they're going to apply it. Here's the data sheet with instructions.

Where is a good place to buy it?

Look for an auto body & paint supply store as they have stocked this for years; it's a staple in auto body shops.
